Antenna Extension for 7530 RTG
The antenna extension has to be selected such that the
horn extends below the nozzle.
If the horn diameter is greater than the nominal width
of the nozzle, the antenna including the extension is
mounted from inside the vessel. The bolts are tightened
from outside, with the instrument lifted up. The
extension has to be selected such that the instrument
can be lifted by at least 100 mm (4”).

UNI Flange
Varec UNI flanges are designed for non-pressurized
operation. Typical pressure fluctuations of breather
valves can be tolerated. The number of bolts has
sometimes been reduced. The bolt-holes have been
enlarged for adaption of dimensions, therefore, the
flange needs to be properly aligned to the
counterflange before the bolts are tightened.
